A total of 185 patients with type 2 diabetes mellitus (T2DM) were consisted of male group (n =95) and postmenopausal female group (n =90).The parameters of fasting plasma glucose,HbA1c,fasting insulin,fasting C peptide,homeostasis model assessment insulin resistant index (HOMA-IR) and β-cell function (HOMA-β),blood lipid,body mass index,and waist to hip ratio were collected and analyzed by Pearson correlation analysis and stepwise multiple regression analysis.The relationships between osteocalcin and these parameters were investigated.The results revealed that osteocalcin was negatively correlated with HbA1C (P＜0.05),and osteocalcin was an independent relevant factor affecting HbA1Clevels.Osteocalcin may be involved in the regulation of glucose metabolism in T2DM.

This article was aimed to study the analgesic and antipyretic effect of Re-Du-Ning (RDN) Injection. Heating model was building on SD rats after subcutaneous injection of yeast. And then, RDN Injection was intravenous injected at the dose of 10.16 g·kg-1, 5.08 g·kg-1, and 2.54 g·kg-1, respectively. Observation was made on changes of rats' temperature. RDN Injection was intravenous injected into ICR mice at the dose of 20.30 g·kg-1, 10.15 g·kg-1, 5.08 g·kg-1 for 7 consecutive days. The methods of mice twist, hot plate and jaw pain were used in the testing of analgesic action of RDN Injection. The results showed that RDN Injection at high and middle dose can significantly reduce the temperature of heating rats models (P < 0.05 or P < 0.01). It can also significantly reduce the twisting times of mice by acetic acid (P< 0.05 or P< 0.01). It can also significantly increase the pain threshold of mice by hot plate and jaw pain (P< 0.05 or P< 0.01). It was concluded that RDN Injection had a good analgesic and antipyretic effect in mice.

Objective:To investigate the characteristics of thymus in patients with COVID-19, and to analyze the CT features and dynamic changes of thymus.Methods:Data of 241 patients diagnosed with COVID-19 admitted to Chongqing Three Gorges Central Hospital from Jan. to Mar. 2020 were retrospectively analyzed, and 242 consecutive subjects were selected as the control group from Nov. to Dec. 2019. The thymus classification, size, and average CT values between COVID-19 patients and the control group were compared, as well as those among different clinical types for COVID-19 patients, before and after treatment, were analyzed.Results:① The attenuation of the thymus: 64.7% (156/241) complete fatty replacement thymus, 17.8% (43/241) predominantly fatty thymus, 11.2% (27/241) approximately one-half fatty and one-half soft-tissue-attenuation thymus, and 6.2% (15/241) predominantly soft-tissue thymus in COVID-19 patients were found. 48.3% (117/242) complete fatty replacement thymus, 25.6% (62/242) predominantly fatty thymus, 10.3% (25/242) approximately one-half fatty and one-half soft-tissue-attenuation thymus, and 15.7% (38/242) predominantly soft-tissue thymus were found in the control group. Complete fatty replacement thymus was an independent factor affecting COVID-19 in 40 to 59 years old patients ( OR=3.071, P=0.000) . The rate of complete fatty replacement thymus: severe or critical type > common type > mild type. ② Size: There was no statistical difference of the thymus size between COVID-19 patients and the control group ( P>0.05) , no statistical difference among the mild type, common type and severe or critical type ( P>0.05) , no statistical difference between before and after treatment ( P>0.05) , and there was no correlation with treatment duration ( r=0.047, r=0.071) . ③ Density: There was no statistical difference of the CT value of thymus between COVID-19 patients and the control group ( P>0.05) , no statistical difference among the mild, common and severe type ( P>0.05) . One patient had a 17 HU increase in thymus density after treatment, but there was no statistical difference in 78 patients in thymus CT values between before and after treatment ( P>0.05) , and there was no correlation with treatment duration (r=0.013) . Conclusions:COVID-19 patients have a high rate of complete fatty replacement thymus. And the heavier the clinical classification, the higher the rate of complete fatty replacement thymus. Complete fatty replacement thymus is a risk factor for COVID-19 patients in 40 to 59 years old.

Objective:To investigate the effect of nursing intervention based on stress system theory on posttraumatic growth (PTG) and social support in patients with stroke.Methods:120 stroke patients who were hospitalized in Department of Neurology, Tangshan People's Hospital from January to August 2018 were selected as the research subjects by convenient sampling. A total of 120 stroke patients were divided into intervention group and control group according to the random number table method with 60 patients in each group. The control group was given routine care, and the intervention group was given stress system intervention on this basis. The Post-traumatic Growth Assessment Inventory (PTGI) and the Perceived Social Support Scale (PSSS) were used to compare the PTG and social support levels of the two groups.Results:After 2 months of intervention, the total score of PTGI in the intervention group was (69.67±9.10) , and that in the control group was (48.62±7.94) , the difference between the two groups was statistically significant ( P<0.05) . After the intervention, the PSSS score of the intervention group was (59.15±13.47) , which was higher than that in the control group (50.87±20.09) , the difference between the two groups was statistically significant ( P<0.05) . Conclusions:Stress system intervention can improve PTG and social support in patients with stroke.

Objective To investigate the roles of long noncoding RNA-myocardial infarction-associated transcript (MIAT) on lens epithelial cells (LECs) fibrosis induced by transforming growth factor-β2(TGF-β2).Methods LECs line (SRA01/04) was cultured in conventional DMEM (normal control group) and DMEM containing 10 ng/ml TGF-β2(TGF-β2 induced group) for 48 hours.The morphology of the cells was observed under the optical microscope,and the relative expression levels of M IAT,E-cadherin (E-cad),α-smooth muscle action (α-SMA),collagen Ⅰ (Coll Ⅰ) in protein level and mRNA level were detected by real-time fluorescence quantitative PCR and Western blot,respectively.The cells cultured in DMEM or DMEM containing 10 ng/ml TGF-β2 were transfected by siNRA empty carrier (siNRA group,siNRA+TGF-β2 group) and siRNA-MIAT (siRNA-MIAT group,siNRA-MIAT+ TGF-β2 group) for 48 hours,and the morphology of the cells was observed under the optical microscope,and the relative expression levels of MIAT,E-cadherin (E-cad),α-smooth muscle action (α-SMA),collagen Ⅰ (Coll Ⅰ) in protein level and mRNA level were detected by real-time fluorescence quantitative PCR and Western blot.Results The cells in the normal control group showed the round and polygon in shape,and those in the TGF-β2 induced group showed the spindle-like.Compared with the normal control group,the relative expression levels of MIAT mRNA,α-SMA mRNA and Coll Ⅰ mRNA were significantly elevated (2.497 ± 0.644 vs.0.827 ± 0.062;2.951 ±0.146 vs.1.085±0.517;2.115 ±0.090 vs.1.002 ± 0.088),and the expression of E-Cad mRNA was significantly reduced (0.102±0.027 vs.1.020±0.262) in the TGF-β2 induced group (P =0.045,0.004,0.000,0.025).The expressions of MIAT,α-SMA,Coll Ⅰ and E-Cad showed a similar trend between two groups.The relative expressions of MIAT protein and mRNA were evidently reduced in the SiRNA-MIAT group compared with the siRNA empty vector group (all at P＜0.05).Compared with the siRNA+TGF-β2 group,the relative expressions of α-SMA and Coll Ⅰ in protein and mRNA levels were significantly reduced,and the expressions of E-cad protwin and mRNA were elevated in the siRNA-MIAT+TGF-β2 group (all at P＜0.01).Conclusions MIAT might participate in TGF-β2-induced LECs-EMT.The down-regulation of MIAT in the LECs inhibits the fibrosis of LECs.

Objective:To observe the effects of 0.01% atropine eye drops on ocular biometrics in myopic adolescents.Methods:A prospective cohort study was conducted.Two hundred and nineteen myopic adolescents who visited the First Affiliated Hospital of Zhengzhou University from June 2016 to June 2017 and completed the 1-year follow-up on time were enrolled.The 219 adolescents were divided into a 0.01% atropine+ single-vision spectacles (SV) group (119 cases) wearing single-vision spectacles with one drop of atropine eye drop applied to both eyes once nightly, and a simple SV group (100 cases) wearing SV only.Axial length (AL), corneal power and anterior chamber depth were measured with the IOLMaster.Lens power was calculated using the Bennett-Rabbetts formula.Intraocular pressure was measured by non-contact tonometry.Spherical equivalent (SE) was examined by cycloplegic autorefraction.Total astigmatism and corneal astigmatism were calculated by vector decomposition.The right eye data were analyzed to compare the ocular biometrics changes between the two groups, and multiple linear regression analysis was used to evaluate the influencing factors.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of First Affiliated Hospital of Zhengzhou University (No.2016-35). Written informed consent was obtained from guardians before any medical examination.Results:The SE change and AL elongation 12 months after treatment in 0.01% atropine+ SV group were (-0.47±0.45) D and (0.37±0.22) mm, respectively, which were significantly lower than (-0.70±0.60)D and (0.46±0.35)mm in simple SV group ( t=5.523, 9.651; both at P<0.001). There were significant differences in SE and AL between before and after treatment in both groups (SE: Fgroup=1.556, P=0.015; Ftime=12.538, P=0.002; AL: Fgroup=3.425, P=0.021; Ftime=18.235, P=0.008). The SE and AL at 4, 8 and 12 months after treatment were all increased in comparison with before treatment in both groups, showing statistically significant differences (all at P<0.001). The SE and AL at 8 and 12 months after treatment in 0.01% atropine+ SV group were smaller than in simple SV group, and the differences were statistically significant (all at P<0.001). At 8 and 12 months after treatment, total astigmatism and the anterior chamber depth were increased and the lens power was decreased in comparison with before treatment in both groups, and the differences were statistically significant (all at P<0.05). There was no significant difference in corneal astigmatism, corneal power and intraocular pressure at different time points before and after treatment between the two groups (all at P>0.05). In the multiple linear regression analysis, an equation of Δmyopic SE=-0.012-2.685×ΔAL-1.002×Δcorneal astigmatism-0.656×Δlens power+ 0.477×Δtotal astigmatism+ 0.363×Δanterior chamber depth-0.060×age+ 0.011×sex was used, showing the change of SE was mainly caused by the change of AL ( β=-2.685), then corneal power, lens power, total astigmatism and anterior chamber depth. Conclusions:In adolescents, 0.01% atropine eye drops can effectively retard myopia progression and axial elongation, showing no effect on astigmatism, corneal power, lens power, anterior chamber depth and intraocular pressure.The controlling effect of 0.01% atropine eye drops in the development of myopia is mainly achieved by reducing axial elongation.

Objective:To observe the long-term efficacy and safety of macular buckling (MB) in the treatment of high myopia traction maculopathy.Methods:A retrospective clinical study. From January 2014 to December 2017, 57 eyes of 57 patients with high myopia traction maculopathy who underwent MB treatment at Zhongshan Ophthalmic Center of Sun Yat-sen University were included in the study. Among them, there were 15 males with 15 eyes, average age was 51.80±10.72 years; there were 42 females with 42 eyes, average age was 59.14±11.51 years. There were 21 eyes of 21 cases with highly myopic macular hole with macular detachment (MHMD), and 36 eyes in 36 cases with highly myopic foveoschisis with macular detachment (FSMD), and they were grouped accordingly. All patients underwent best corrected visual acuity (BCVA), optical coherence tomography (OCT), and axial length (AL) measurements. The standard logarithmic visual acuity chart was used for BCVA examination, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All patients underwent MB, either on its own or combined with vitrectomy. Patients with significant vitreous macular traction on OCT were treated with combined surgery. One, 3, 6 months and 1, 2, 3, and 4 years after the operation, the same equipment and methods before the operation were used to conduct related examinations, and the long-term efficacy and safety of the two groups of eyes were observed.Results:Before surgery, the logMAR BCVA of eyes in MHMD group and FSMD group were 1.35±0.47 and 1.17±0.59, respectively; 4 years after surgery, they were 1.02±0.49 and 0.73±0.55, respectively. The BCVA improved significantly at postoperative 4 years than preoperative in both groups ( P=0.039, 0.001). In the eyes with MHMD, the BCVA was found to be significant improved 3 years after surgery ( P=0.042). Whereas, in the eyes with FSMD, the BCVA was found to be significantly improved 3 months after surgery ( P=0.013). Macular reattachment was achieved in 100% of cases, while macular hole closure rate was achieved in 66.7% in the MHMD group. In the FSMD group, either macular reattachment rate or the foveoschisis resolution rate was 97.2%. After surgery, choroidal neovascularization was observed in 2 eyes, and 3 eyes with intraretinal cyst. Conclusion:MB may represent a safe and effective surgical option for the treatment of high myopia maculopathy.
